Be it known that I, ULYssEs S. lVnnDINonew and useful Improvements in, OiLGas Burners, of which the following is a specification.

This invention relates toimprovements in fuel oil burners.

An object of the invention resides in providing a fuel oil burner, wherein the air supply is directed downwardly in an annular form, around: a. breaker plate against which is: projected an upwardly directed stream of-fuel'oil, under pressure, sothat the air will readily vaporize the fuel leaving said breaker plate in the form of a substantially fine vapor, for subsequentcombustion.

Another object of; the invention resides in providing a fuel oil: burner, having an;

annular o-ilreceiving cup, a central, supply pipe extending through said cup for direct;- ing a supply of fuel oil upwardly, under, a substantial pressure forprojecting it beyond the cup, to engage a breaker, plate mounted above; saidcup and the end-S. of said 'l'e ed pipeuso that the breaker platewill'cause the stream of projected-fuel oil to be broken up into finely divided form, in' a direction downwardly toward said fuel cup, an air. supply structure beingfprovided over said fuel cup having. an outlet around the, breaker plate, so that heated air will act on the finely divided fuel; forquickly vaporizing the same, for the purposes of combustion, the heat of combustion heating the air supply means, so that the same is preheated before its contract with the vapors discharged from said breaker plate.

A further object of the invention is to provide a burner having an upwardly projected jet of fuel. adapted to impinge against the breaker plate and to be subsequently vaporized by air directed downwardly in concentricrelation with the projected fuel for vaporizing the fuel discharged in finely divided form from said breaker plate for combustion, in order to produce complete combustion of the fuel oil, and an exceedingly hot flame.

The invention comprehends other objects and improvements in the details ofconstruction and arrangement of parts, which are mor particularly described in the following de a ed de p ia nd: t. h l ims. rec ted toapreferred form of the ention, t be ng und rsteo t h eve a e 'i t nemay be, made in the. construction with rangeuient of the parts without departing from the scope the invention as, described and claimech f 1 i i In the drawing, fprn ing a part of thisap phcat on Th'eligure shows a vertical sectional View through, aburner constructed according-to the inyention, i i i i i 1 indicates the base of. the burner whichds of an r ular form and provided with, nularrecess 2, onthe under sidethereof, the central. portion having an annul'andepres} sion 3 forming atrough at excessivelouei flow. of fuel, fron t I QOUi let pipe, whilethe central portion is prov ded with' a cup aanq a pair of. annular channels 6 arrangedfiii. concentri e rel no around the cup 5 an d in stepped i'gelation thereto. The qentual por i tion of the cup is formed witha vertical l I 1 opening for receiving the fuel fee-d, p pe 7, i

the. upper. end of which projects slightly, above the horizontal plane of theupperfend (rfthe cup 5, as clearly shown in the,d ',a,w iug. ,u high pipeis ac apted to pr oje ct a rather small stream f-fuelupwardly under ihstantial i' or'ce for a p-uiflpose w vhichw ill a se earre rs The baseil; is formedat diametrically opi PQSi Q po nt t tsleeve ex e w .91mi? ed to receive and mount the. downturne-d ends of an air.heatingmember 11, which is hollowin section, and the inteigioif' offwhich communicates with the recess 2 of the base, so that the supply of air is received through the recess 2, the tubular extension 8, and is directed upwardly to be heated in the horizontal portion 10 of the heating member for subsequent projection downwardly through the depending central outlet 11, which is of annular form, and ofa size to overlie the outer annular channel 6, it being arranged in spaced relation above said channel. A rod 12 is mounted in the upper wall of the heating member 9, and depends in the central portion in axial relation with the depending air outlet 11, for supporting the breaker plate 13, in horizontal concentric relation slightly above the lower end of the outlet 11, and directly above the fuel feed pipe 7. The breaker plate is arranged so that the heated air being discharged therefrom will be directed downwardly in an annular path, against the annular channel 6, for vaporizing any liquid fuel contained therein.

In the use of a burner of this type, priming fuel is placed in the cup 5 and the annular channels 6 for heating the air heating member 9, so that the air for the combustion of the fuel oil will be reheated. In the normal operation of the burner, the fuel oil is projected from the relatively small fuel feed pipe 7 upwardly against the central portion of the breaker plate 13, so that said late will break the stream of fuel into a finely divided form, discharging it outwardly in all directions, and downwardly toward the annular channel 6 and the cup 5, the downward blast of heated air around said breaker plate contacting with the finely divided fuel, and effectively vaporizing the same before it reaches the channels 6, in the cup 5, and also vaporizing any fuel in said channels, and cups, combustion taking place immediately upon the mixture of the air with the finely divided fuel which will produce complete combustion of the fuel oil, and an exceedingly hot flame, which will superheat the air heating member 9, so that all of the air passing therethrough under the normal operation of the burner will be superheated for more readily vaporizing and aiding in the combustion of the fuel oil.

From the foregoing description, it will be clear that a fuel oil burner has been provided which is adapted for use in furnaces, stoves or the like, or in any other form of apparatus where such a burner is useful which would utilize a relative small quantity of fuel oil, adapted to be mixed with a suflicient quantity of air to insure the complete combustion thereof, and to form a hot flame, and at the same time reduce the likelihood of the formation of carbon in any quantity.

lVhat is claimed is:

V 1. An oil gas burner comprising a base provided with air discharge openings and provided at its center with an oil receiving cup, an air supplying and heating duct disposed over said base and having downturned ends connected to said discharge openin said duct being formed with an air outlet disposed over said cup, a discular oil breaker plate disposed in said outlet and spaced therefrom to provide an annular passage for the discharging air, said plate being spaced above the edge of said outlet, and an oil L feed pipe extending through said cup and terminating beneath said plate, said pipe being adapted to project oil under pressure against the under side of said plate to be vaporized and fixed with the discharging and heated air, whereby to form a com bustible gaseous mixture.

2. An oil gas burner comprising a substantially annular base provided with air escape necks at diametrically opposite points and provided with a central depression simultaneously forming an overflow trough and a central projection, the top of said projection being formed with radially spaced annular grooves and with, a central depression forming an oil receiving cup, an air heating duct disposed above said base and having down turned ends connected with the aforesaid escape necks, said duct being formed with a dependingtubular air discharge disposed over the aforesaid projection, one of the aforesaid grooves being disposed beyond said discharge, a discular breaker plate arranged within said air discharge and having its peripheral edge spaced from the wall of said discharge to provide an annular and restricted air passage, said plate being disposed above the edge of said discharge, and a fuel feed pipe extending upwardly through the aforesaid cup and terminating in spaced relation below the under side of said plate.

In testimony whereof I'aflix my signature.
